Licenshantering av programvaror i enkommunal verksamhet : En fallstudie över licenshanteringen i Falu kommun

Forskningen visar att förändringar av informationsteknologin och en ökande anskaffning av nya programvaror har lett till underliggande problem som kan drabba heterogena programvarulicensmiljöer och stora organisationer. Underliggande problem i den stora kontexten är mjukvaruhantering. Licenshantering av programvaror är just en förgrening av det stora problemet. Stora organisationer som en kommunal verksamhet är drabbad av det här underliggande problemet på grund av komplexitet hos organisationens miljö. Att tillämpa förändringar i området programvarulicens är omöjligt utan att göra förändringar i hela den organisationsprocess som följer med det. Fallstudiens uppdrag är ett nytt omfattande område kring licenshantering av programvaror som kan vara väldigt lärorikt och en bra erfarenhet att ta del av. Uppsatsen beskriver hur en kommunal verksamhets licenshantering av programvaror ser ut och de problem som finns med den nuvarande licenshanteringsprocessen. Förarbetet med en litteraturstudie tillsammans med datagenereringsmetoderna intervjuer, dokumentstudier och observationer används för att studera fallet på djupet. Målet är att kunna ta fram de nuvarande problem som finns, analysera dem och ge rekommendation för åtgärder som det studerade fallobjektet, Falu Kommuns IT-kontor, kan använda. En rekommendation för en tydlig licenshanteringsprocessmodell anses vara ett bra akademiskt bidrag eftersom problemet med licenshanteringen av programvaror är ett generellt problem. Uppsatsens resultat är en processmodell om licenshantering av programvaror för organisationer med IT-tjänstkunder. Det är en generisk lösning som skulle kunna användas av andra kommunverksamheter och liknande organisationer.

Melhoria do pilar "manutenção planejada" da TPM através da utilização do RCM para nortear as estratégias de manutenção

O atual ambiente competitivo, onde baixo custo, alta qualidade e um grau crescente de customização são exigências para a sobrevivência das empresas, tem influenciado as ações dos profissionais de manutenção com vistas ao aprimoramento das políticas de manutenção. Como resultado, tem-se na área de manutenção industrial, uma grande quantidade de métodos, software, modelos e ferramentas de gestão disponíveis. Dentre eles, dois métodos se destacam: o RCM (Reliability Centered Maintenance ou Manutenção Centrada em Confiabilidade), de origem norte-americana, e a TPM (Total Productive Maintenance ou Manutenção Produtiva Total), de origem japonesa. A TPM promove a integração total entre homem, máquina e empresa, onde a manutenção dos meios de produção passa a constituir uma responsabilidade de todos. A utilização da TPM contempla a implementação de pilares de sustentação, sendo um deles, a manutenção planejada. Entretanto, a TPM não especifica a estratégia a ser adotada pela manutenção planejada. O RCM é uma metodologia lógica de procedimentos que objetiva estabelecer uma manutenção preditiva e preventiva para alcançar, de maneira efetiva e eficiente, os níveis de segurança e confiabilidade requeridas para cada equipamento. Considerando um ambiente com a TPM já implementada, o objetivo deste trabalho é a melhoria do pilar Manutenção Planejada da TPM através da utilização do RCM para nortear as estratégias de manutenção em empresas industriais. A sistemática proposta é ilustrada através de um estudo de caso na indústria de conformação de metais.

O impacto das práticas ITIL na flexibilidade organizacional - evidências empíricas em uma empresa multinacional de TI

The present work has as main objective the identification and impact analysis for the practice ITIL in the organizational flexibility of a multinational IT company, being this study of quali-quantitative and exploratory nature. To achieve this objective, some theoretical studies on bureaucracy, organization flexibility, control, IT governance and ITIL were done, as a form to better understand the research problem. For analysis effect a set of eleven ITIL process was considered in this research ¿ service desk, incident management, problem management, change management, configuration management, release management, service level management, availability management, capacity management, continuity management and finally IT financial services management ¿ grouped in its two core areas ¿ service support and service delivery. Then a scale was constructed and validated, on the basis of theoretical models developed by Volberda (1997), Tenório (2002) and Golden and Powell (1999), to measure the flexibility related to each process comprising the ITIL core. The dimensions adopted to measure flexibility were: organization design task, managerial task, IT impact on work force, HR management, efficiency impact, sensitivity, versatility and robustness. The instrument used in research was a semi-structured interview, which was divided in two parts. The data collection was performed with ten interviewed people from an IT multinational company, based on convenience, some were managers and there were users, some were ITIL certified and others not. The statistic tests of t student and Wilcoxon non-parametric were adopted. The result of the research indicated that the ITIL service support area, for possessing greater operational focus, presents flexibility trend. The opposite was found for the service delivery area, which has greater tactical focus. The results also suggest that the change management discipline was the one that contributed for the most flexibility inside the company, followed by incident management discipline and the service desk function.

Alinhamento de expectativas e desempenho organizacional: um estudo sobre os métodos ágeis de gestão.

A adoção dos métodos ágeis de gestão do desenvolvimento de software tem sido uma tendência mundial, considerando-se as empresas do setor de tecnologia. Empresas brasileiras atuando neste mercado não estão apartadas deste quadro, uma vez que o objetivo desses métodos é endereçar um cenário comum a qualquer uma dessas organizações: lidar com a dificuldade de modelar adequadamente os problemas usualmente complexos que são objetivo da construção de um software e com a mudança constante de requisitos que esta situação representa, potencializada ainda mais pela dinâmica frenética da disseminação da informação no século XXI, além de modificar um quadro crônico de fracassos e falhas no setor, visando entregar produtos de qualidade aos seus clientes com o máximo de velocidade. Aspectos internos como o aumento de produtividade e a redução de retrabalho também fazem parte dos objetivos de adoção destas metodologias. O presente estudo visa avaliar os aspectos humanos e culturais envolvidos e identificar a convergência entre as expectativas da empresa e dos empregados quando da adoção de métodos ágeis de gestão, a partir de pesquisa de campo que capturou as reações de um grupo de entrevistados à implantação desses métodos na Módulo Security Solutions, empresa brasileira de tecnologia e serviços, após dois anos de uso interno abrangente. Os resultados apontam para o sucesso da implantação, com reação positiva dos empregados, a despeito da necessidade de endereçamento de aspectos humanos para ajuste do modelo e do impacto negativo da cultura local e organizacional terem sido amplamente percebidos.

Network reconfiguration and loss allocation in a deregulated environment of distribution systems

Low flexibility and reliability in the operation of radial distribution networks make those systems be constructed with extra equipment as sectionalising switches in order to reconfigure the network, so the operation quality of the network can be improved. Thus, sectionalising switches are used for fault isolation and for configuration management (reconfiguration). Moreover, distribution systems are being impacted by the increasing insertion of distributed generators. Hence, distributed generation became one of the relevant parameters in the evaluation of systems reconfiguration. Distributed generation may affect distribution networks operation in various ways, causing noticeable impacts depending on its location. Thus, the loss allocation problem becomes more important considering the possibility of open access to the distribution networks. In this work, a graphic simulator for distribution networks with reconfiguration and loss allocation functions, is presented. Reconfiguration problem is solved through a heuristic methodology, using a robust power flow algorithm based on the current summation backward-forward technique, considering distributed generation. Four different loss allocation methods (Zbus, Direct Loss Coefficient, Substitution and Marginal Loss Coefficient) are implemented and compared. Results for a 32-bus medium voltage distribution network, are presented and discussed.

Malware distributed collection and pre-classification system using honeypot technology

Malware has become a major threat in the last years due to the ease of spread through the Internet. Malware detection has become difficult with the use of compression, polymorphic methods and techniques to detect and disable security software. Those and other obfuscation techniques pose a problem for detection and classification schemes that analyze malware behavior. In this paper we propose a distributed architecture to improve malware collection using different honeypot technologies to increase the variety of malware collected. We also present a daemon tool developed to grab malware distributed through spam and a pre-classification technique that uses antivirus technology to separate malware in generic classes. © 2009 SPIE.

Kostenorientiertes Controlling von E-Learning-Plattformen mit dem TCO-Konzept

Zur administrativen Unterstützung von Lehr- und Lernprozessen werden E-Learning-Plattformen eingesetzt, die auf der Grundlage des Internet Funktionen zur Distribution von Lehr- und Lernmaterialien und zur Kommunikation zwischen Lehrenden und Lernenden anbieten. Zahlreiche wissenschaftliche Beiträge und Marktstudien beschäftigen sich mit der multikriteriellen Evaluation dieser Softwareprodukte zur informatorischen Fundierung strategischer Investitionsentscheidungen. Demgegenüber werden Instrumente zum kostenorientierten Controlling von E-Learning-Plattformen allenfalls marginal thematisiert. Dieser Beitrag greift daher das Konzept der Total Cost of Ownership (TCO) auf, das einen methodischen Ansatzpunkt zur Schaffung von Kostentransparenz von E-Learning-Plattformen bildet. Aufbauend auf den konzeptionellen Grundlagen werden Problembereiche und Anwendungspotenziale für das kostenorientierte Controlling von LMS identifiziert. Zur softwaregestützten Konstruktion und Analyse von TCO-Modellen wird das Open Source-Werkzeug TCO-Tool eingeführt und seine Anwendung anhand eines synthetischen Fallbeispiels erörtert. Abschließend erfolgt die Identifikation weiterführender Entwicklungsperspektiven des TCO-Konzepts im Kontext des E-Learning. Die dargestellte Thematik ist nicht nur von theoretischem Interesse, sondern adressiert auch den steigenden Bedarf von Akteuren aus der Bildungspraxis nach Instrumenten zur informatorischen Fundierung von Investitions- und Desinvestitionsentscheidungen im Umfeld des E-Learning.

Model Driven Architecture (MDA): Integration and Model Reuse for Open Source eLearning Platforms

Open Source (OS) community offers numerous eLearning platforms of both types: Learning Management Systems (LMS) and Learning Content Systems (LCS). General purpose OS intermediaries such as SourceForge, ObjectWeb, Apache or specialized intermediaries like CampusSource reduce the cost to locate such eLearning platforms. Still, it is impossible to directly compare the functionalities of those OS software products without performing detailed testing on each product. Some articles available from eLearning Wikipedia show comparisons between eLearning platforms which can help, but at the end they barely serve as documentation which are becoming out of date quickly [1]. The absence of integration activities between OS eLearning platforms - which are sometimes quite similar in terms of functionalities and implementation technologies - is sometimes critical since most of the OS projects possess small financial and human resources. This paper shows a possible solution for these barriers of OS eLearning platforms. We propose the Model Driven Architecture (MDA) concept to capture functionalities and to identify similarities between available OS eLearning platforms. This contribution evolved from a fruitful discussion at the 2nd CampusSource Developer Conference at the University of Muenster (27th August 2004).

Metamodelo para la definición, implantación y mejora de los procesos de gestión de proyectos

En los últimos años hemos sido testigos de la creciente demanda de software para resolver problemas cada vez más complejos y de mayor valor agregado. Bajo estas circunstancias, nos podemos hacer la siguiente pregunta: ¿Está preparada la industria de software para entregar el software que se necesita en los próximos años, de acuerdo con las demandas del cliente? Hoy en día, muchos expertos creen que el éxito de esta industria dependerá de su capacidad para gestionar los proyectos, las personas y los recursos. En este sentido, la gestión de proyectos es un factor clave para el éxito de los proyectos software en todo el mundo. Además, considerando que las Pequeñas y Medianas Empresas de software (PYMEs) representan el 99,87% de las empresas españolas, es vital para este tipo de empresas la implementación de los procesos involucrados con la gestión de proyectos. Es cierto que existen muchos modelos que mejoran la eficacia de la gestión de proyectos, pero la mayoría de ellos se centra únicamente en dos procesos: la planificación del proyecto y la monitorización y control del proyecto, ninguno de los cuales a menudo es asequible para las PYMEs. Estos modelos se basan en el consenso de un grupo de trabajo designado para establecer cómo debe ser gestionado el proceso software. Los modelos son bastante útiles ya que proporcionan lineamientos generales sobre dónde empezar a mejorar la gestión de los proyectos, y en qué orden, a personas que no saben cómo hacerlo. Sin embargo, como se ha dicho anteriormente, la mayoría de estos modelos solamente funcionan en escenarios dentro de las grandes empresas. Por lo tanto, es necesario adaptar los modelos y herramientas para el contexto de PYMEs. Esta tesis doctoral presenta una solución complementaria basada en la aplicación de un metamodelo. Este metamodelo es creado para mejorar la calidad de los procesos de la gestión de proyectos a través de la incorporación de prácticas eficaces identificadas a través del análisis y estudio de los modelos y normas existentes relacionadas con la gestión de proyectos. viii ProMEP – Metamodelo para la gestión de proyectos Por lo tanto, el metamodelo PROMEP (Gestión de Proyectos basada en Prácticas Efectivas) permitirá establecer un proceso estándar de gestión de proyectos que puede adaptarse a los proyectos de cada empresa a través de dos pasos: En primer lugar, para obtener una fotografía instantánea (o base) de los procesos de gestión de proyectos de las PYMEs se creó un cuestionario de dos fases para identificar tanto las prácticas realizadas y como las no realizadas. El cuestionario propuesto se basa en el Modelo de Madurez y Capacidad Integrado para el Desarrollo v1.2 (CMMI-DEV v1.2). Como resultado adicional, se espera que la aplicación de este cuestionario ayude a las PYMEs a identificar aquellas prácticas que se llevan a cabo, pero no son documentadas, aquellas que necesitan más atención, y aquellas que no se realizan debido a la mala gestión o al desconocimiento. En segundo lugar, para apoyar fácilmente y eficazmente las tareas de gestión de proyectos software del metamodelo PROMEP, se diseñó una biblioteca de activos de proceso (PAL) para apoyar la definición de los procesos de gestión de proyectos y realizar una gestión cuantitativa de cada proyecto de las PYMEs. Ambos pasos se han implementado como una herramienta computacional que apoya nuestro enfoque de metamodelo. En concreto, la presente investigación propone la construcción del metamodelo PROMEP para aquellas PYMEs que desarrollan productos software de tal forma que les permita planificar, monitorizar y controlar sus proyectos software, identificar los riesgos y tomar las medidas correctivas necesarias, establecer y mantener un conjunto de activos de proceso, definir un mecanismo cuantitativo para predecir el rendimiento de los procesos, y obtener información de mejora. Por lo tanto, nuestro estudio sugiere un metamodelo alternativo para lograr mayores niveles de rendimiento en los entornos de PYMEs. Así, el objetivo principal de esta tesis es ayudar a reducir los excesos de trabajo y el tiempo de entrega, y aumentar así la calidad del software producido en este tipo de organizaciones. Abstract In recent years we have been witnessing the increasing demand for software to solve more and more complex tasks and greater added value. Under these circumstances, we can ourselves the following question: Is the software industry prepared to deliver the software that is needed in the coming years, according to client demands? Nowadays, many experts believe that the industry’ success will depend on its capacity to manage the projects, people and resources. In this sense, project management is a key factor for software project success around the world. Moreover, taking into account that small and medium-sized software enterprises (SMSe) are the 99.87% of the Spanish enterprises, it is vital for this type of enterprises to implement the processes involved in project management. It is true that there are many models that improve the project management effectiveness, but most of them are focused only on two processes: project planning and project monitoring and control, neither of which is affordable for SMSe. Such models are based on the consensus of a designated working group on how software process should be managed. They are very useful in that they provide general guidelines on where to start improving the project management, and in which order, to people who do not know how to do it. However, as we said, the majority of these models have only worked in scenarios within large companies. So, it is necessary to adapt these models and tools to the context of SMSe. A complementary solution based on the implementation of a metamodel is presented in this thesis. This metamodel is created to improve the quality of project management processes through the incorporation of effective practices identified through the analysis and study of relevant models and standards related to project management. Thus, the PROMEP (PROject Management based on Effective Practices) metamodel will allow establishing a project management standard process to be tailored to each enterprise’s project through two steps: Firstly, to obtain a baseline snapshot of project management processes in SMSe a two-phase questionnaire was created to identify both performed and nonperformed practices. The x ProMEP – Metamodelo para la gestión de proyectos proposed questionnaire is based on Capability Maturity Model Integration for Development v1.2. As additional result, it is expected that the application of the questionnaire to the processes will help SMSe to identify those practices which are performed but not documented, which practices need more attention, and which are not implemented due to bad management or unawareness. Secondly, to easily an effectively support the software project management tasks in the PROMEP metamodel, a Process Asset Library (PAL) is designed to support the definition of project management processes and to achieve quantitative project management in SMSe. Both steps have been implemented as a computational tool that supports our metamodel approach. Concretely, the present research proposes the accomplishment of the PROMEP metamodel for those SMSe which develop software products and enable them to plan, supervise and control their software projects, identify risks and take corrective actions, establish and maintain a set of process assets, define quantitative models that predict the process performance, and provide improvement information. So, our study suggests an alternative metamodel to achieve higher performance levels in the SMSe environments. The main objective of this thesis is help to reduce software overruns and delivery time, and increase software quality in these types of organizations.

Fiabilidad de minimodulos de silicio

El objetivo de este Proyecto Final de Carrera es la realización de un ensayo de fiabilidad de componentes electrónicos, más concretamente de Minimódulos de Silicio, con el fin de estudiar su comportamiento a lo largo del tiempo de vida. Debido a la larga duración de los Minimódulos de Silicio , un ensayo de este tipo podría durar años, por lo que es necesario realizar un ensayo acelerado que acorte significativamente el tiempo del experimento, para ello, han de someterse a esfuerzos mayores que en condiciones normales de funcionamiento. A día de hoy, los Minimódulos de silicio, que conocemos como placas solares fotovoltaicas, se usan en infinidad de dispositivos debido a las múltiples ventajas que conllevan. La principal ventaja es poder llevar electricidad a cualquier parte del planeta sin necesidad de tener que hacer unas elevadas inversiones. Esta electricidad proviene de una fuente de energía inagotable y nada contaminante, con lo que ayudamos a mantener el equilibrio del planeta. La mayoría de las veces estas placas solares fotovoltaicas se usan en el exterior, soportando cambios de temperatura y de humedad elevados, de ahí, la importancia de realizar ensayos de fiabilidad, que muestren sus posibles causas de fallo, los efectos que producen estos fallos y los aspectos de diseño, fabricación y mantenimiento que puedan afectarles. Los Minimódulos de silicio utilizados en este proyecto son el modelo MC-SP0.8-NF-GCS de la empresa fabricante Multicomp. Para realizar el Proyecto hubiéramos necesitado una cámara climática que simulara unas condiciones ambientales determinadas, pero debido a la dificultad de iluminar el módulo dentro de la cámara climática hemos desarrollado un nuevo sistema de ensayos acelerados en temperatura. El nuevo sistema de ensayos acelerados consiste en: •Colocar los módulos fotovoltaicos en el laboratorio con un foco de 500W que irradia lo equivalente al sol. •Los tres módulos trabajarán a tres temperaturas diferentes para simular condiciones ambientales distintas, concretamente a 60°C, 72°C y 84°C. •Mediante un sistema automático de medida diseñado en LabVIEW, de manera simultánea tomará medidas de tensión en las tres placas y estudiaremos el grado degradación en cada placa. Se analizaran los resultados obtenido de cada una de las medidas y se realizará un estudio de fiabilidad y del proceso de degradación sufrido por los Minimódulos de silicio. Este PFC se puede dividir en las siguientes fases de trabajo siendo el ensayo la parte más larga en el tiempo: •Búsqueda de bibliografía documentación y normas aplicables. •Familiarización con los equipos y software, estudiando el manejo del software que viene con el Multímetro Keithley 2601 y el programa LabVIEW. •Desarrollo del hardware y sistemas necesarios para la realización del ensayo. •Montaje del ensayo •Realización del ensayo. •Análisis de resultados. ABSTRACT. The objective of this Final Project is conducting a test reliability of electronic components, more specifically Silicon minimodules, in order to study their behavior throughout the life span. Due to the long duration of Silicon minimodules a test like this could take years, so it is necessary to perform an accelerated significantly shorten the time of the experiment, testing for it, should be subjected to greater efforts than in normal operating. Today, the mini-modules, silicon is known as photovoltaic solar panels are used in a multitude of devices due to the many advantages they bring. The main advantage is to bring electricity to anywhere in the world without having to make high investments. This electricity comes from an inexhaustible source of energy and no pollution, thus helping to maintain the balance of the planet. Most of the time these solar photovoltaic panels are used on the outside, enduring changes in temperature and high humidity, hence, the importance of reliability testing, showing the possible causes of failure, the effects produced by these faults and aspects of design, manufacturing and maintenance that may affect them. The silicon mini-modules used in this project are the MC-SP0.8-NF-GCS model Multicomp manufacturing company. To realize the project we would have needed a climatic chamber to simulate specific environmental conditions, but due to the difficulty of illuminating the module in the climate chamber we have developed a new system of accelerated tests in temperature. The new system is accelerated tests: •Place the PV modules in the laboratory with a focus on the equivalent 500W radiating sun. •The three modules work at three different temperatures to simulate different environmental conditions, namely at 60 °C, 72 °C and 84 °C. •Automatic measurement system designed in LabVIEW, simultaneous voltage measurements taken at the three plates and study the degradation degree in each plate. The results obtained from each of the measurements and a feasibility study and degradation suffered by the silicon is performed minimodules were analyzed. This PFC can be divided into the following phases of the test work the longest part being overtime: •Literature search and documentation standards. •Familiarization with equipment and software, studying management software that comes with the Keithley 2601 multimeter and the LabVIEW program. •Development of hardware and systems necessary for the conduct of the trial. •Experiment setup •Carrying out the experiment. •Analysis of results.

Desarrollo de frameworks con .NET

La expansión experimentada por la informática, las nuevas tecnologías e internet en los últimos años, no solo viene dada por la evolución del hardware subyacente, sino por la evolución del desarrollo de software y del crecimiento del número de desarrolladores. Este incremento ha hecho evolucionar el software de unos sistemas de gestión basados en ficheros, prácticamente sin interfaz gráfico y de unos pocos miles de líneas a grandes sistemas distribuidos multiplataforma. El desarrollo de estos grandes sistemas, requiere gran cantidad de personas involucradas en el desarrollo, y que las herramientas de desarrollo hayan crecido también para facilitar su análisis, diseño, codificación, pruebas, implantación y mantenimiento. La base de estas herramientas software las proveen las propias plataformas de desarrollo, pero la experiencia de los desarrolladores puede aportar un sinfín de utilidades y de técnicas que agilicen los desarrollos y cumplan los requisitos del software en base a la reutilización de soluciones lo suficientemente probadas y optimizadas. Dichas herramientas se agrupan ordenadamente, creando así frameworks personalizados, con herramientas de todo tipo, clases, controles, interfaces, patrones de diseño, de tal manera que se dan soluciones personalizadas a un amplio número de problemas para emplearlas cuantas veces se quiera, bien marcando directrices de desarrollo mediante el uso de patrones, bien con la encapsulación de complejidades de tal modo que los desarrolladores ya dispongan de componentes que asuman cierta lógica o cierta complejidad aliviando así la fase de construcción. En este trabajo se abordan temas sobre las tecnologías base y plataformas de desarrollo para poder acometer la creación de un framework personalizado, necesidades a evaluar antes de acometerlo, y técnicas a emplear para la consecución del mismo, orientadas a la documentación, mantenimiento y extensión del framework. La exposición teórica consiste en mostrar y evaluar los requisitos para crear un framework, requisitos de la plataforma de desarrollo, y explicar cómo funcionan las grandes plataformas de desarrollo actuales, que elementos los componen y su funcionamiento, así como marcar ciertas pautas de estructuración y nomenclatura que el desarrollo de un framework debe contemplar para su mantenimiento y extensión. En la parte metodológica se ha usado un subconjunto de Métrica V3, ya que para el desarrollo de controles no aplica dicha metodología en su totalidad, pero contempla el catálogo de requisitos, los casos de uso, diagramas de clase, diagramas de secuencia, etc… Aparte de los conceptos teóricos, se presenta un caso práctico con fines didácticos de cómo parametrizar y configurar el desarrollo bajo la plataforma .NET. Dicho caso práctico consiste en la extensión de un control de usuario genérico de la plataforma .NET, de tal modo que se aplican conceptos más allá del hecho de crear funciones como las funcionalidades que puede brindar un API. Conceptos sobre como extender y modificar controles ya existentes, que interactúan por medio de eventos con otros controles, con vistas a que ese nuevo control forme parte de una biblioteca de controles de usuario personalizados ampliamente divulgada. Los controles de usuario son algo que no solo tienen una parte funcional, sino que también tienen una parte visual, y definiciones funcionales distintas de las típicas del software de gestión, puesto que han de controlar eventos, visualizaciones mientras se dan estos eventos y requisitos no funcionales de optimización de rendimiento, etc… Para el caso práctico se toma como herramienta la plataforma de desarrollo .Net Framework, en todas sus versiones, ya que el control a extender es el control ListView y hacerlo editable. Este control está presente en todas las versiones de .NET framework y con un alto grado de reutilización. Esta extensión muestra además como se puede migrar fácilmente este tipo de extensiones sobre todos los frameworks. Los entornos de desarrollo usados son varias versiones de Visual Studio para el mostrar dicha compatibilidad, aunque el desarrollo que acompaña este documento esté realizado sobre Visual Studio 2013. ABSTRACT The expansion in computer science, new technologies and the Internet in recent years, not only is given by the evolution of the underlying hardware, but for the evolution of software development and the growing number of developers. This increase has evolved software from management systems based on files almost without graphical interface and a few thousand of code lines, to large multiplatform distributed systems. The development of these large systems, require lots of people involved in development, and development tools have also grown to facilitate analysis, design, coding, testing, deployment and maintenance. The basis of these software tools are providing by their own development platforms, but the experience of the developers can bring a lot of utilities and techniques to speed up developments and meet the requirements of software reuse based on sufficiently proven solutions and optimized. These tools are grouped neatly, creating in this way custom frameworks, with tools of all types, classes, controls, interfaces, design patterns,… in such a way that they provide customized solutions to a wide range of problems to use them many times as you want to occur, either by dialing development guidelines by using patterns or along with the encapsulation of complexities, so that developers already have components that take some logic or some complexity relieving the construction phase. This paper cover matters based on technologies and development platforms to undertake the creation of a custom framework, needs to evaluate before rush it and techniques to use in order to achieve it, a part from techniques oriented to documentation, maintenance and framework extension. The theoretical explanation consists in to demonstrate and to evaluate the requirements for creating a framework, development platform requirements, and explain how large current development platforms work, which elements compose them and their operation work, as well as mark certain patterns of structure and nomenclature that the development of a framework should include for its maintenance and extension. In the methodological part, a subset of Métrica V3 has been used, because of, for the development of custom controls this methodology does not apply in its entirety, but provides a catalogue of requirements, use cases, class diagrams, sequence diagrams, etc ... Apart from the theoretical concepts, a study case for teaching purposes about how to parameterize and configure the development under the .NET platform is presented. This study case involves the extension of a generic user control of the .NET platform, so that concepts apply beyond the fact of creating functions as the functionalities that can provide an API. Concepts on how to extend and modify existing controls that interact through events with other controls, overlooking that new control as a part of a custom user controls library widely publicized. User controls are something that not only have a functional part, but also have a visual part, and various functional definitions of typical management software, since that they have to control events, visualizations while these events are given and not functional of performance optimization requirements, etc ... For the study case the development platform .Net Framework is taken as tool, in all its versions, considering that control to extend is the ListView control and make it editable. This control is present in all versions of .NET framework and with a high degree of reuse. This extension also shows how you can easily migrate these extensions on all frameworks. The used development environments are several versions of Visual Studio to show that compatibility, although the development that accompanies this document is done on Visual Studio 2013.

Aspects of the design and operation of production control systems in manufacturing industry

Computerised production control developments have concentrated on Manufacturing Resources Planning (MRP II) systems. The literature suggests however, that despite the massive investment in hardware, software and management education, successful implementation of such systems in manufacturing industries has proved difficult. This thesis reviews the development of production planning and control systems, in particular, investigates the causes of failures in implementing MRP/MRP II systems in industrial environments and argues that the centralised and top-down planning structure, as well as the routine operational methodology of such systems, is inherently prone to failure. The thesis reviews the control benefits of cellular manufacturing systems but concludes that in more dynamic manufacturing environments, techniques such as Kanban are inappropriate. The basic shortcomings of MRP II systems are highlighted and a new enhanced operational methodology based on distributed planning and control principles is introduced. Distributed Manufacturing Resources Planning (DMRP), was developed as a capacity sensitive production planning and control solution for cellular manufacturing environments. The system utilises cell based, independently operated MRP II systems, integrated into a plant-wide control system through a Local Area Network. The potential benefits of adopting the system in industrial environments is discussed and the results of computer simulation experiments to compare the performance of the DMRP system against the conventional MRP II systems presented. DMRP methodology is shown to offer significant potential advantages which include ease of implementation, cost effectiveness, capacity sensitivity, shorter manufacturing lead times, lower working in progress levels and improved customer service.

Model Configuration And Data Management In The Short-Term Water Information Forecasting Tools

The Short-term Water Information and Forecasting Tools (SWIFT) is a suite of tools for flood and short-term streamflow forecasting, consisting of a collection of hydrologic model components and utilities. Catchments are modeled using conceptual subareas and a node-link structure for channel routing. The tools comprise modules for calibration, model state updating, output error correction, ensemble runs and data assimilation. Given the combinatorial nature of the modelling experiments and the sub-daily time steps typically used for simulations, the volume of model configurations and time series data is substantial and its management is not trivial. SWIFT is currently used mostly for research purposes but has also been used operationally, with intersecting but significantly different requirements. Early versions of SWIFT used mostly ad-hoc text files handled via Fortran code, with limited use of netCDF for time series data. The configuration and data handling modules have since been redesigned. The model configuration now follows a design where the data model is decoupled from the on-disk persistence mechanism. For research purposes the preferred on-disk format is JSON, to leverage numerous software libraries in a variety of languages, while retaining the legacy option of custom tab-separated text formats when it is a preferred access arrangement for the researcher. By decoupling data model and data persistence, it is much easier to interchangeably use for instance relational databases to provide stricter provenance and audit trail capabilities in an operational flood forecasting context. For the time series data, given the volume and required throughput, text based formats are usually inadequate. A schema derived from CF conventions has been designed to efficiently handle time series for SWIFT.
